The WPS series from Winters Instruments, a manufacturer of pressure and temperature instrumentation, is a low-pressure differential switch for monitoring and controlling air and nonaggressive gases.
Designed to handle pressure, vacuum, and differential pressures, the WPS is ideal for HVAC applications and simple to integrate into BAS systems. The simple-to-use adjustment knob allows for field changes to be made without the use of a reference pressure gauge. The sensitive silicone diaphragm is able to sense pressure as low as 0.08 inches of water (16 Pa) up to 20 inches of water (4,000 Pa).
